1 Ciaim.

This invention relates to devices for use in connection with the manufacture or repair of cemented type leather or textile shoes, or the like, and more particularly to an improved form of pad for supporting, for example, a shoe sole during pressing and gluing of a lasted shoe against the sole.

One of the objects of the invention is to provide an improved shoe part supporting pad of the self heating type wherein an improved form of heating element is incorporated to provide advantages in connection with the maintenance and repair thereof. Other objects and advantages will appear from the specification hereinafter.

In connection with the manufacture or repair of cemented type shoes it is a present practice to support, for example, the sole part upon a resilient pad while pressing theelasted shoe part against the sole until such time as the cement providing the connection therebetween has become thoroughly set. For this purpose it is also the present practice to heat the sole supporting pad by some suitable medium such as by circulating a hot liquid through the interior of the pad or by mounting an electrical resistance heating element within the body of the pad, so as to elevate the temperature of the pad during the pressing operation in order to shorten the time required to provide complete setting of the cement. The present invention relates more specifically to an improved form of supporting pad incorporating the electrical resistance type of heating element, whereby the heating element may be readily withdrawn from the body of the pad and replaced whenever necessary, in an improved manner.

In the drawing:

Fig. 1 is a plan of a heating pad of the invention, with a portion broken away to show the interior thereof; and

Fig. 2 is a side elevation thereof.

The drawing exemplifies the invention as comprising a pad member ID formed of rubber composition material or the like, which i generally shaped in plan View similar to the shape of a shoe sole. The upper face of the pad 10 is dished as at 12 to complement the naturally curving shape of the shoe sole to be supported by the pad.

The pad heating means of the invention comprises a generally U shaped conduit 14 embedded within the body of the pad member iii in such manner as to lie adjacent the upper face thereof and so as to be contiguous to the side edges thereof. Thus, the conduit l4 lies approximately below the cemented joint to be procured between the edges of the lasted shoe and the sole piece. An electrical resistance element IS in the form of a wire of any suitable metallic alloy substance is provided with a covering l8 of asbestos or the like, and the insulated element It is threaded through the conduit M as illustrated by the drawing. The ends of the resistance element are arranged to extend beyond the corresponding ends of the conduit H for connection to suitable electrical conductors (not shown) which in turn connect to a suitable source of electrical energy, as will be understood by those skilled in the art. Thus, the shoe pad is adapted to be heated, as required, by transmission of electrical current through the resistance wire IE to hasten the setting of the cement of the cementing operation.

Thus, the specific arrangement of the heating element wire [6 within the conduit l4 provides means whereby the heating element wire may be readily threaded through the conduit as required to repair the wire element whenever the latter becomes burned out or broken or otherwise incapable of continuing in operation. In such event the damaged heating element is simply Withdrawn from the conduit by pulling upon its exposed ends, and a new heating element may be installed by threading it endwise through the conduit into the operative position shown in Fig. 1. Thus, the heating element of the device may b replaced as required without disturbing the mounting of the conduit within the pad l0, and it is no longer necessary to discard the pad member simply because the heating element becomes damaged and unworkable. Consequently, the use of my improved shoe press pad provides improved economies and advantages not found in press pads of the prior art.

Although only one form of the invention has been shown and described in detail, it will be apparent to those skilled in the art that the invention is not so limited but that various changes may be made therein without departing from the spirit of the invention or the scope of the appended claim.

What is claimed is:

A shoe sole part press pad for use in the operation of pressing together cemented shoe sole and upper parts, said pad comprising a body of resilient material having a dished upper surface of shoe sole-like planform adapted to support thereon a shoe sole part for pressing the latter into cemented relation against another shoe part, a conduit member of relatively rigid material fixedly embedded within said pad body and so arranged as to lie substantially parallel to the planform periphery of said pad to provide a smoothly curving generally U-shaped open passageway through the body of said pad from points of entry and exit therefrom at the heel end of said pad, said conduit being also arranged to be dis- I duit and inserted therein to extend therethrough and to terminate exteriorly of said pad for connection to an electrical power source and to pro ide a continuous electrical circuit through said pad, said conduit and said insulated wire being so relatively dimensioned that said wire is freely withdrawable from said conduit so a to be replaceable bysliding insertion'of a similar substitute Wire into said conduit by feeding the substitutje wire wi'th an en'dwise motion into said conduit until it is threaded'therethrough.
